اللَّهُمَّ يَا مُقَلِّبَ الْقُلُوبِ ثَبِّتْ قَلْبِي عَلَى دِينِكَ
Allahumma ya Muqallibal-qulub thabbit qalbi 'ala dinik
O Allah, O Turner of hearts, make my heart firm upon Your religion.
The most frequently made du'a of the Prophet ﷺ according to some narrations. If the Prophet himself ﷺ — guaranteed Paradise — felt the need to constantly ask for firmness in faith, then no one is safe from deviation. Your heart is literally between Allah's fingers, turned as He wills. The only security is asking Him to hold it steady. Make this du'a every single day.
